If you have been quick to scoop up new iPhones as they come out, you may have a couple of old models lying around right now. How about using them to start a server farm?

The prototype pictured here is intended to promote the ServersMan app, which gives iPhone users the ability to use their phone as network storage, file viewer or a mini web server. Hey, If you are not going to sell the phones or give them away, its better than leaving them in a drawer somewhere. [IT Media via DVICE]
